Access-Control-Allow-Origin error

[akerd]

Hello, I know that plugin is a bit old but is a good starting point to start learning how to integrate GoodBarber with external API.

I uploaded the code on GoodBarber but I receive the following error in console when loading the plugin page.

Failed to load https://api.wunderground.com/api//conditions/q/40.728527,-73.987427.json: The 'Access-Control-Allow-Origin' header has a value 'http://www.wunderground.com' that is not equal to the supplied origin. Origin 'https://<my_site>' is therefore not allowed access.

Is there something that I miss here? Is it still possible this kind of integration with external websites or the API should be hosted only on the same domain where is hosted also the GoodBarber application?
